Bob Wachter on Twitter: "SF folks: it's now a big-time surge. No longer just cases (~500/d reported, so true # >2K, or ~250/100K/d). Also major uptick in hospitalizations: 98 in SF (vs 18 six wks ago). @UCSFHospitals 41 pts in hospital, twice April #. If you're trying to stay well, time to up your game. https://t.co/VNmhHal5EL" / Twitter
